Parameters

filter	Filter type: Norm or Welsch.
dataType	Data type flavors.
dstRoiSize	Size of the source and destination ROI in pixels.
numChannels	Number of channels.
pSpecSize	Pointer to the size (in bytes) of the specification structure.
pBufInitSize	Pointer to the size (in bytes) of the init temp buffer.
pBufferSize	Pointer to the size (in bytes) of the work buffer.

Description

This function computes the size of the buffers required for filtering operations. Call this function before using the ippiFilterILSInit and ippiFilterILS functions.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsStepErr	Indicates an error condition if one of the steps has a zero or negative value.
ippStsSizeErr	Indicates an error condition if one of the fields of dstRoiSize has a zero or negative value.
